Green Grass Without Cropsie Value Plus One

I know that cropsies that do not need to be collected never get bonus counts, the little plus (+) numbers on them. But if a cropsie needs to be collected to win then its value will increment sometimes. I understood that green grass always gave a bonus count of plus one (+1) minimum for required cropsies.  However, I noticed on level 480 that it did not. More than one kind of required cropsies were on the green grass but they had no plus one value. Isn't that a defect?
